ABSTRACT:
A method, system and computer program is disclosed for reducing range and angular ambiguities in a target data matrix output from a real beam monopulse radar sensor within a single beam for use in terrain morphing applications employed by brownout take-off and landing aid systems. One or more range bins are calculated to selectively determine one or more range segments from one or more targets of interest. Range resolution enhancement processing is employed to the selectively determined one or more range segments to obtain a range of target scatter locations. A monopulse angle bin is estimated from the obtained range of target scatter locations and one or more control inputs. Elevation and azimuth angular binning is applied to the estimated monopulse angle bin to obtain a smaller coverage area among one or more possible target areas. One or more shortest-range bins in a two-dimensional (2D) azimuth and elevation grid is selected from the smaller coverage area, which generate the target data output matrix from the selected one or more shortest-range bins in the two-dimensional (2D) azimuth and elevation grid.
